When compared to soft, heterogeneous or granular materials, hard and homogeneous materials are able to reflect sound waves more efficiently.
Three factors, such as beam spreading, attenuation and scattering, control the distance a sound wave will pass in a particular medium.
We thus forever try to catch up, updating to remain the same.
